Rumor has it that “Real Housewives of Beverly Hills” could be down two original stars next season.

Radar Online reports that Kim Richards is on her way out, and her sister Kyle might not be far behind.

“The network is not entirely happy with the ratings for the current season of ‘Beverly Hills’ and sadly, despite being Paris Hilton’s aunt, she has little going on in her life,” a production insider tells Radar. “Viewers don’t care about watching Kim’s dog getting training. It’s boring!”

Sources add that Kyle Richards is threatening to walk if her sister is pushed out of the Bravo reality hit.

“As you can imagine, Kyle is unhappy about Bravo’s plans. She has made no secret of that fact, that she’ll threaten to quit if her sister is fired,” another source tells Radar.

Ratings for the season have reportedly been on the rise since the feud between Brandi Glanville and “RHOBH” newbie Joyce Giraud has started heating up.

“Real Housewives of Beverly Hills” airs Mondays at 8pm on Bravo. Should the show ditch Kim and Kyle? Weigh in below!
